AI Technical Summary
Technical Problem
Reactor systems for producing light olefins face challenges in evenly heating and drying refractory linings, which can lead to mechanical stress and inefficiencies during startup.
Method used
A method involving the controlled passage of a gaseous fluid through a reactor system, with specific flow rates and temperature increments, to evenly heat and dry refractory materials, reducing mechanical stress and enhancing system reliability.
Benefits of technology
The method ensures a relatively even heating of reactor system components, effectively drying refractory linings and reducing mechanical stress, thereby enhancing the reliability and efficiency of the reactor system during startup.

Abstract
Methods for heating reactor systems include passing a gaseous fluid to a regenerator at a first flow rate and passing a first portion of the gaseous fluid present in the regenerator to a reactor at a second flow rate from 50% to 80% of the first flow rate. The methods include passing a first portion of the gaseous fluid present in the reactor out of the reactor in a reactor outflow stream, passing a first portion of the reactor outflow stream back to the reactor, and passing a second portion of the reactor outflow stream out of the reactor system at a third flow rate from 10% to 50% of the first flow rate. The methods include passing a second portion of the gaseous fluid present in the reactor out of the reactor system at a fourth flow rate from 10% to 50% of the first flow rate. A temperature of the gaseous fluid passed to the regenerator is increased, over a time period, by greater than or equal to 100 °C.
